1994 Ford Mustang Roush Induction System

You won’t see too many of these Roush induction systems. Originally pitched to Ford as an OE unit, this Roush intake manifold became part of the Stage 3 program when Ford shifted gears into modular engine development. Paired with Roush CNC-ported GT-40 heads, this three-piece manifold was designed to boost 5.0-liter performance by up to 120 horsepower. The intake alone was said to benefit a 5.0 with 47 extra ponies, and with stock GT-40 heads it promised a 99 hp bump. Originally developed for the SN-95 Mustang, this intake was also offered as an upgrade kit for Fox Mustangs, and there was even an optional supercharger inlet kit to plumb boost into the rear-inlet throttle body.
